title: The effect of chlorpromazine on transformation in Bacillus subtilis.
abstract: In the presence of the widely used tranquilizer, chlorpromazine, transforming DNA of Bacillus subtilis is photoinactivated by long-wave ultraviolet light. The loss of biological activity is predominantly caused by lack of binding of the DNA to recipient cells and the introduction of single-strand breaks in the treated DNA.
